"Their teeth look great," the vet said, during a recent check-up of my two pooches. "How often do you brush them?"
I don't brush my dogs' teeth; I think that's an insane thing to do. And I'm not about to pay somebody $600 to do it. I just regularly give them marrow bones, as the act of using their teeth to rip raw meat off of a bone, followed by scraping every last inch of that bone clean, keeps their teeth clean naturally.
It would be awesome if eating corn on the cob would automatically keep human teeth clean, but sadly that's not the case. And I'd never heard of an alternative to the toothbrush, toothpaste and water we all use to keep our teeth clean--until now.
A British company is busily flogging their Rolly Chewable Toothbrush, a small, fugu-looking thing that you pop into your mouth and manipulate around using your tongue. The bristles are coated in Xylitol and flouride, and there's no water needed.

I know, it sounds crazy. But it's so crazy that it just, might, work.
Presumably the company sank most of their money into R&D—and decided to save a few bucks on advertising:
Still, I'm dying to try one of these things.

http://www.fuzzybrush.com is the less pretty version you can get in the restrooms of British rest stops and I think some restaurants/bars. I did try one once, it was a pretty strange feeling, definitely something you'd need practice at!
Looks like a good idea.
We all brush the delicate layers of enamel off our teeth every day. Apparently flossing is much better than brushing for decay prevention.
I'd just be worried about people swallowing something so small.
I just buy some marrow bones and I use my teeth to rip the meat off the bone. My teeth look just like your dog's...but without the pointy bits.
This has Xylitol in it which can kill your dog! Do not use this on your dog!
Africans have been using this for centuries:

I've alway heard of apples referred to as nature's toothbrush for their similar effects to marrow bones.
Just don't inhale sharply or this will be scrubbing the inside of your intestines clean too
I submitted a similar concept into the Core77/Pop-Sci challenge
in 2004. Check out the Dental Pods in the Honorable Mention category. http://www.core77.com/challenge/humanpower/
